changed nodePopup to costumer wishes, now supports only showing the finctions that have a visible effect
selected menu reworked to make it work with functionality provided by the NodePopup. deleted some unnessecary static stuff in NodePopup (dosent belong there) tweaked the NodePopup so that it looks for the appropriate cell itsself, adjusted drawHirerchy(...) so that it deselects lastSelected to prevent side effects
accordeon now makes proper use of threads, now the programm works properly on a dualcore mashine :P
nodepopup bug fixed
